What’s ARP.EXE (TCP/IP Arp Command)? Is it safe or a virus?

ARP.EXE is a Microsoft Windows command-line utility that manages the Address Resolution Protocol (ARP) cache, which maps IP addresses to physical MAC addresses on a local network. It allows users to display, add, or remove entries in the ARP cache, helping resolve communication issues between devices by ensuring correct IP-to-MAC address associations. The tool is typically used for network troubleshooting and diagnostics in TCP/IP-based networks. For instance, it can be used to view the current ARP table, manually set static ARP entries, or clear the cache to resolve conflicts or refresh network connections.

What does it mean if someone is the publisher of a PC .exe (executable or process)?

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
